‘It comes in waves’ I say to Monique as she asks me how I’m feeling. I’m referring to alternate moments of excitement and sheer panic. She’s just picked me up from the expo where I’ve registered, collected my numbers, had a browse, and generally started to feel sick. Its finally here. I’m really going to do this. Getting  up this morning at 3:45 was a bit of a shocker, saw a couple of familiar faces at Cape Town Airport, and the plane was packed with tracksuits and running shoes.
